When to see a doctor

Make an appointment with your doctor if you have any signs or symptoms that worry you.

Atypical hyperplasia typically doesn't cause symptoms, but it may cause changes to appear on a mammogram. Atypical hyperplasia is usually discovered during a breast biopsy to investigate an abnormality found on a mammogram. Sometimes atypical hyperplasia is discovered on a biopsy done for a different condition.
